A good example of this is how many "back-end guys" here think it's Javascript and web tech that are hard/annoying instead of all client tech due to the nature of building user-facing software that has to run on a 1,000,000 devices instead of sysops-facing software that runs on one server.
Be wary of anyone who just peddles downsides without acknowledging trade-offs. They don't have much experience (You can have 20+ years of dev experience while inexplicably avoiding this sort of realization). Right now there's someone in the top thread saying they literally don't know a single company that didn't regret using Angular/React. Oh bother. This sort of person just has to ask, but they don't because they prefer to cling on to their little sneering world view.
If someone seriously can't say why anyone could prefer React (or any other tech, like JS or PHP or jQuery) without a cynical disparaging trait like these people are just idiots, simply write this person off and seek more even-keeled opinions about the world.
I love HN, but I would really be wary of taking too much front end type commentary seriously as it comes from HN comments.
Now sometimes the comments are GREAT, that's not to say it is all bad, but other times the comments on front end topics on HN is like walking into a meeting with a bunch of managers and non front end focused folks who got together to list their gripes ;) In those cases I often don't say anything because the ranting is on and nobody really cares.
Edit: This was longer but I decided I didn't want to go that far down the meta rabbit hole.
